You might want to re-visit my link on Stringers. The use of CSM is no longer a pre-requisite. The 1708 has CSM on it and is now acceptable to be used alone without the additional layer of CSM. 2 Layers of 1708 to tab in the Stringers should be more than adequate. I would recommend tearing some strips of CSM to cap the stringers for waterproofing.
